| 摘 要： | 比较分析20世纪2次最强El Nino事件(1982/1983年与1997/1998年)珠江口表层海温(SST)的变化差异,发现造成其差异的原因:一是到达地面的太阳总辐射1982/1983年高于1997/1998年;二是南海高压势力1982/1983年弱于1997/1998年;三是1982/1983年冬季风速比1997/1998年大1~2 m/s。

| Abstract: | By comparative analysis on the SST variations in Pearl River estuary,the reasons that caused the difference of SST variations during two strongest El Nino events of 20th century in 1982/1983 and 1997/1998 are investigated.Results show that the total solar irradiance that reached the ground was higher in 1982/1983 than that in 1997/1998,South China Sea high pressure was weaker in 1982/1983 than that in 1997/1998,and the winter wind speed was 1 ~ 2 m/s greater in 1982/1983 than that in 1997/1998.And these can be of important references for SST forecasting in Pearl River estuary. |
